Question

49 : 7 + (80-69) - 5 85 - (82 - 28) : 6 - 1456 : 8 × 7 + 3 × (94 - 77)700 - 10 × (95 : 5)

Answer 1

1)13,2)62, 3)100, 4)510

Answer 2

Let's solve the expression step by step:

1. 49 : 7 + (80-69) - 5 = 7 + 11 - 5 = 13

2. 85 - (82 - 28) : 6 - 1456 : 8 × 7 + 3 × (94 - 77) = 85 - 54 : 6 - 182 : 8 + 3 × 17 = 85 - 9 - 22 + 51 = 105

3. 700 - 10 × (95 : 5) = 700 - 10 × 19 = 700 - 190 = 510

Putting it all together:

13 + 105 + 510 = 628

So, the final result is 628.
